Answer:
So option (a) is correct option
Explanation:
We have given final speed of the car = 23 m/sec
And initial speed of the car = 30 m/sec
Time in which speed is decreases t = 2 sec
From first equation of motion we know that v = u+at
So acceleration
Negative sign indicate that acceleration will be in opposite direction
So
So option (a) is correct option
A periodic wave has a fixed pattern that is repeated. One completion of the wave pattern is called as cycle of the wave.
<u>Explanation:
</u>
Periodic waves are those which repeat the same kind of behaviour or pattern after a particular interval of time. So, completion of behaviour or pattern for a given time interval is termed as the cycle of wave.
Generally, one complete wave pattern makes a time interval of 2π. So each cycle will take nearly 2π time to form. The repetition of cycle in a time interval will help us to derive the frequency of the system.
Answer:
10.05volts
Explanation:
Work done to move a charge from the positive side of a plate to the negative side is represented mathematically as 1/2CV² which is also the energy stored by the capacitor.
Work done = 1/2CV² where
C is the charge
V is voltage difference that exists between the plates.
Given Work done = 101Joules
C = 2Coulombs
Substituting the values in the formula to get V, we will have;
101 = 1/2(2)V²
101 = V²
V = √101
V = 10.05volts
Therefore the voltage difference between the plates is 10.05colt's
Answer: Accordingly, what is the difference between an epiphyseal plate and an epiphyseal line? The Epiphyseal plate contains cartilage used for producing bone. The Epiphyseal line is formed after the epiphyseal plate has stopped producing bone). The Periosteum is the covering of a bone.
